This book was released on 2017-08-10 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato virus Y (PVY) infects a wide host range mainly within the Solanaceae and is distributed worldwide. PVY is transmitted by more than 40 aphid species in a non persistent manner. Isolates of the PVY species are highly variable at biological, serological and molecular levels. Epidemiological studies have highlighted the emergence of distinct potato PVY variants able to induce necroses on potato tubers. Due to the lack of efficient resistance to PVY isolates inducing necrotic symptoms in cultivated varieties and the plant-to-plant transmission of isolates through the daughter tubers, PVY has become the most economically important virus for the potato industry. The review offers an overview of several decades of research on PVY but also focuses on the latest data obtained by expert on PVY worldwide on the biological characteristics of PVY, interactions between aphids-hosts, its evolution and management. Identified knowledge gaps to understand further PVY biology will be discussed.

Download or read book The Potato Crop written by Hugo Campos and published by Springer Nature. This book was released on 2019-12-03 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.

Download or read book Studies on the Epidemiology of Potato Viruses in the Northeastern USA and the Biology of Potato Virus Y written by Phillip Mark Baldauf and published by . This book was released on 2007 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato viruses cause significant potato yield loss world wide. It is important to understand the nature of the potato virus populations present in a geographical region in order to develop appropriate control strategies. A wide-ranging survey of potato viruses in potatoes being grown in the northeastern USA had never been done. A survey of six potato viruses, Potato virus A (PVA), Potato virus M (PVM), Potato virus S (PVS), Potato virus X (PVX), Potato virus Y (PVY), and Potato leafroll virus (PLRV), was conducted in New York and Maine during 2002 and 2003. Leaf samples were tested by ELISA and PVY-positive samples were further tested to determine if a necrotic strain of PVY (PVYN, PVYN:O, or PVYNTN) was present. In both years, PVY and PVS were identified in a majority of the samples, and mixed infections predominated in 83% of the symptomatic leaves in 2002. Of the total 394 PVY-positive samples, three reacted with monoclonal antibody (MAb) 1F5 and caused veinal necrosis (VN) in tobacco. Two of these isolates caused tuber necrosis in the potato cv. Yukon Gold. Three PVY isolates reacted with MAb 1F5 but did not cause VN in tobacco, and two caused VN but did not react with MAb 1F5. Two of the necrotic PVY isolates collected, along with a PVYO isolate, were used to conduct multi-year experiments to determine the impact of PVY strain, potato cultivar, and time of infection on marketable yield and tuber infection efficiency. It was found that final disease incidence in the field could not be used to predict tuber infection, as inoculated plants testing negative in the field produced infected tubers. PVY infection decreased marketable yield, but yield was dependent on the potato cultivar and inoculation time. PVY infected between 25 and 100% of the marketable tubers. Our results suggest that, compared with other isolates, necrotic strains of PVY might be less effectively removed in seed potato production systems and this may explain the emergence of necrotic strains.

Download or read book Multilateral Interactions In The Rhizosphere written by Soumitra Paul Chowdhury and published by Frontiers Media SA. This book was released on 2023-09-05 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rhizosphere is an ecological hotspot. Plant roots, bacteria, archaea, fungi, nematodes, and other macroscopic organisms interact here with each other. Plants represent the main influencing force as they produce a mixture of chemical molecules and extrude them in the form of root exudates. Those exudates determine not only the nutrient availability of the plant but also influence the outcome of the interactions in the vicinity of the roots. In response to the plant-derived signals, a subset of the bulk soil microbes can proliferate in the proximity of the root and some of them can eventually overcome the plant defense system to colonize the plants. The root-associated microbiota is assumed to be crucial for plant health, and belowground plant-microbe and microbe-microbe interactions can result in altered growth and nutritional quality of the aboveground plant parts. Such interactions affect community composition and productivity in natural ecosystems or crop yield in agricultural fields. Root associations with plant growth-promoting rhizobacteria (PGPR) producing phytohormones that alter root architecture, or produce antibiotics to suppress antagonistic pathogens, affecting nutrient availability and competition between plants are just a few among many examples of such belowground interactions in the rhizosphere. Moreover, the role of rhizosphere microorganisms in stimulating the plant immune system leading to Induced Systemic Resistance (ISR) has also been a focus of an active investigation. However, the molecular mechanisms are still largely unknown. On one hand, it has been proposed that plants actively recruit beneficial microorganisms under certain pathological conditions or influence the soil microbial communities and create a so-called “soil memory”, which is conveyed to future plant generations. On the other, the presence and interactions between microorganisms in the soil have a substantial impact on plant health.
